Radio astronomy encompasses microwave astronomy, submillimeter astronomy, and those bands with longer wavelengths than microwaves. Radar astronomy is a technological use of microwaves to locate rocky objects.

There are 89 unique areas of the celestial sphere from which radio waves can irradiate the Earth. Ideally, there would be a first source from each of these areas.

As radio astronomy has been in use since the early twentieth century, a radio source has a good chance of also being a first source for any constellation.

Research

Hypothesis:

  1. The first radio source was detected in a northern hemisphere constellation.

Control groups

The findings demonstrate a statistically systematic change from the status quo or the control group.

“In the design of experiments, treatments [or special properties or characteristics] are applied to [or observed in] experimental units in the treatment group(s).[1] In comparative experiments, members of the complementary group, the control group, receive either no treatment or a standard treatment.[2]"[3]

Proof of concept

Def. a “short and/or incomplete realization of a certain method or idea to demonstrate its feasibility"[4] is called a proof of concept.

Def. evidence that demonstrates that a concept is possible is called proof of concept.

The proof-of-concept structure consists of

  1. background,
  2. procedures,
  3. findings, and
  4. interpretation.[5]
